Depending on accompanying components, you may also want to consider Classe. I am presently using Classe CAM 200's as a temporary substitute for Atma-Sphere MA-2's. Combined with a Jadis preamp the presentation is very musical with little sacrifice in the frequency extremes. I must state that I was expecting a large drop-off in listening pleasure, moving from OTL to solid state, but I have been pleasanly surprised. The CAM's are nice, yet I have read that Classe Omega takes the experience further.
